What is this tool?
This large file downloader fetches a file from a direct URL in your browser. Click Analyze to see the file name, size, type and whether the server accepts range requests. If it does, the file is split across several parallel connections, and every piece is checked against the server's 206 Partial Content reply so a server that ignores ranges cannot corrupt the file. Pause really stops the transfer. Resume continues from the last received byte, even after a page reload or a dropped connection. In Chrome and Edge you can save straight to disk while downloading, which avoids holding big files in memory. You can also queue several links (or paste a whole list), check a SHA-256 checksum, cap the bandwidth and add mirror URLs. The file streams from the source server to your device and is never uploaded to Wivrix. The one exception: if a server blocks cross-origin (CORS) requests and you agree to use the proxy, the download goes through file-proxy.wivrix.com.
How to Use
- Paste a direct link into File URL, for example https://example.com/big-file.zip, and press Analyze (or Enter).
- Check the file size, type, and whether the server is splittable. Keep Auto connections or drag the slider.
- Optionally tick Save straight to disk (Chrome and Edge) and pick where the file goes. Advanced options add a SHA-256 checksum, a bandwidth limit or mirror URLs.
- Press Download. Use Pause and Resume at any time; an unfinished download is offered again the next time you analyze the same link.
- When it finishes, preview the file if its type is supported, then press Save file. Files saved to disk are already in place.
- To fetch several files, use Add to queue or paste a list under Add several URLs to the queue, then press Start queue.
Frequently Asked Questions
Why does it say single stream only?
Parallel connections need HTTP range requests. If the server does not support them, or answers a range request with the whole file (status 200 instead of 206), the tool downloads the file as one stream instead.
Does Resume really continue where it stopped?
Yes. The tool tracks every byte range it has received. Pause aborts the open requests, and Resume asks the server only for the missing ranges. Progress is stored in your browser (IndexedDB), so after a reload, analyze the same link and press Resume download. If the server's file changed in the meantime, the tool starts over instead of mixing two versions.
Can I download very large files?
Yes. In Chrome and Edge, tick Save straight to disk so data is written to the file as it arrives, with no memory limit. Other browsers hold the whole file in memory until you save it, which needs about the file size in RAM.
Why do I get a CORS error, and what does the proxy do?
Some servers block downloads started by scripts on other websites. If you agree, the tool routes the request through file-proxy.wivrix.com on Cloudflare's network, up to 2 GB per file. The proxy can see the file URL. You can also enter your own proxy or turn it off in Proxy settings.
How does the download queue work?
Add links one at a time or paste a list (one URL per line). Nothing starts until you press Start queue. Items download one after another and each finished file is saved automatically. The queue is remembered in this browser, and it never restarts on its own when you come back.
